    Raymond Brown Minerals & Recycling (RBMR)


    Longparish, Hampshire



    RBMR has been processing Incinerator Bottom Ash Aggregate (IBAA) discharged from Hampshire’s three energy recovery facilities at Marchwood, Portsmouth and Chineham, for several years. The IBAA has cement-like properties so can act as an excellent substitute for natural aggregates. This can be used in road sub-base, bulk fill, asphalts, foamed concrete and cement bound materials. The Highways Agency also accepts the use of processed IBAA as an aggregate for bound and unbound layers in road construction.

    This new facility was constructed within the grounds of the existing materials recycling facility at Longparish. The processing area was cut out to a specific fall with all surplus material re-used on site to create screening bunds. The project comprised large scale earthworks, construction of a lagoon for leachate containment, two new weighbridges, a concrete access road and a large concrete material storage and sorting area for the processed IBAA.

    Located adjacent to the busy A303, the site shares access to the materials recycling facility, MOD units, and other businesses. Close attention was paid to the traffic management plan which required careful phasing and programming to allow recycling site traffic movements and access to other users throughout.

    our sectors

    Malcolm & I would like to thank yourself and Guy for working with us and our design team in delivering a superb finished product for FloPlast that we are very proud of and which has been much admired by our customers on site visits.  So far so good, we are finding our operational feet on the site and it all appears to be working well.

    - Bryan Lynch, Floplast

    Knights Brown performed very well on this project in terms of quality, cost and time. The team worked very well as part of an integrated delivery team with the Employer to the benefit of the project

    - Marc Bryan, Portsmouth City Council

    Sites are always very well presented. First impressions count and if a site looks well organised and clean when you arrive then generally this is applied throughout the management of the projects. Indeed, all five projects I am Cummins PM for, have been managed to a high standard and equally the safety records and standards are very good.

    - Iain Brooks, Cummins

    Site staff were pleased to have had Knights Brown on the team, they were proactive from day one to the end towards potential issues and responsive to a changing site environment for works.
